/**
 @class GridLoader
 The GridLoader is working in conjuction with the Grid and responsible
 for loading and unloading object-types (one or more) when objects
 enters a grid.  Unloading is scheduled and might be canceled if
 an interested object re-enters.  GridLoader does not do the actuall
 loading and unloading but implements as a template pattern that
 delicate its loading and unloading for the actualy loader and unloader.
 GridLoader manages the grid (both local and remote).
